Troubleshooting 7-13 I Determine whether or not the Compaq servers support the physical SCSI disks installed in the RA4000/RA4100 Arrays. Check the event log for disk I/O error messages or indications of problems with the communications transport. I If the drives are still not recognized, it is recommended that you start investigating the problem from the lowest level of drive configuration. G Run the Compaq Array Configuration Utility. You can run this utility online if at least one logical drive is configured and recognized. The Array Configuration Utility is used to see if any of the drive arrays are offline (degraded or failed). The online utility is installed as part of the Compaq SmartStart and Support Software CD. G If all drives are not recognized by the Array Configuration Utility, it is probably a physical connection problem. G Verify that the indicator lights on the Fibre Host Adapters, Fibre Channel SAN Switches, FC-AL Switches, or Storage Hubs and RA4000 Array Controller are showing correct status. G Verify that the shortwave Gigabit Interface Converters (GBICs) are properly seated in the Fibre Host Adapters, Fibre Channel SAN Switches, FC-AL Switches, or Storage Hubs and RA4000 Array Controllers. G Verify that all Fibre Channel cables are properly connected to their Gigabit Interface Converter-Shortwave (GBIC-SW) modules. For details on how to connect the GBIC-SW modules and the Fibre Channel cables, refer to the Compaq StorageWorks RAID Array 4000 User Guide or the Compaq StorageWorks RAID Array 4100 User Guide. I If all drives are recognized by the Array Configuration Utility and are configured correctly, start Windows 2000 Advanced Server and run Disk Management. Verify that all drive volumes can be accurately viewed from Disk Management on each node. I If you continue to have problems, refer to Appendix A, "Diagnosing and Resolving Shared Disk Problems," for further information. Also refer to the Compaq Fibre Channel Troubleshooting Guide for further corrective actions.
